Taking certain antidepressants for depression is linked to a heightened risk of subsequent mania and bipolar disorder, reveals research published in the online journal BMJ Open.

The strongest association seemed to be for serotonin reuptake inhibitors, or SSRIs for short, and the dual action antidepressant venlafaxine, the analysis indicated.

The researchers base their findings on the anonymised medical records of more than 21,000 adults in receipt of treatment for major (unipolar) depression between 2006 and 2013 at a large provider of inpatient and community mental healthcare in London.

New research shows a cereal familiar today as birdseed was carried across Eurasia by ancient shepherds and herders laying the foundation, in combination with the new crops they encountered, of 'multi-crop' agriculture and the rise of settled societies. Archaeologists say 'forgotten' millet has a role to play in modern crop diversity and today's food security debate.

The domestication of the small-seeded cereal millet in North China around 10,000 years ago created the perfect crop to bridge the gap between nomadic hunter-gathering and organised agriculture in Neolithic Eurasia, and may offer solutions to modern food security, according to new research.

A team of chemists from ITMO University, in collaboration with research company SOPOT, has developed a novel type of firefighting foam based on inorganic silica nanoparticles. The new foam beats existing analogues in fire extinguishing capacity, thermal and mechanical stability and biocompatibility. The results of the study were published in ACS Advanced Materials & Interfaces.

CHAMPAIGN, Ill. -- A new study finds that pre-adolescent children who have sustained sports-related concussions have impaired brain function two years following injury.

The results are published in the International Journal of Psychophysiology.

Over a million brain injuries are treated annually in the U.S. While organized sports at all levels have implemented safety protocols for preventing and treating head injuries, most pediatric concussions still result from athletic activities.

Climate change is rapidly heating up lakes around the world, threatening freshwater supplies and ecosystems across the planet, according to a study spanning six continents.

More than 60 scientists took part in the research, published in the journal Geophysical Research Letters and announced today at the fall meeting of the American Geophysical Union.
